'- GRATE-YBARHI if bars of the class having detachable fuel-bearings, and has for its object to improve the construction and increase the efficiency of devices of this character.

With these and other objects-in view,

which will appear as the nature of the invention is better understood, the invention consists of certain novel features of construction, as hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, and in which cor-- responding parts are denoted by like designating characters, is illustrated the preferred form of the embodiment of the invention capable of carrying the same into practical operation.

Figure 1 is a perspective of one of the improved grate-bars with one of the fuel-bearings in partly-detached position. Fig. 2 is a perspective view of a modified form of bar.

ig. 3 is a perspective view of the modified form of fuel-bearing employed upon the form of bar shown in Fig. 2. Fig. 4 is a plan View of portions of the improved grate-bars arranged side by side to illustrate their coactive relations. 1

The improved device when applied comprises in general a plurality of supportin devices having means for suspending t em spaced apart in the fire-chamber anda plurality of interchangeable fuel-supports, each embracing in its construction an elongated plate, the plate adapted to be supported end to end upon the supporting devices with their upper faces flush with each other and also flush with the end portions of the supporting devices and each plate also having a plurality of spaced lateral wings.

The supporting devices are formed with end bearings 12 13, depending portions 22.23, and connecting-bars between the lower ends of the depending portions.

The connecting-bars may be arran ed in pairs spaced apart, as at and 11 in igs. 1 and 4, or in a single-bar, as at 14 in Fi 2.

The elongated lates which form t e central portions of t e fuel-bearings are represented at 16 and are adapted to be arranged Specification of Letters Patent. Application filed retr'm 17, 1906. SerialNo. 301,644.

- end to end between the depending portions 22 23,"with the end plates abutting against the same and with their u per-faces flush with each other and also flusli with the upper faces of the end bearings 12 13.

The lateral wings are represented at 17 and are so arranged that the several wings of each fuel-bearing correspond to and bear against the wings of the adjacent bearing, as represented in Fig. 4.

II The wings are preferably inclined to the plane of the plate 16, from which they extend, as shown.

When the structure shown in Fig. 1 is employed, the lateral wings 17 bear upon the ars 1O 11, and the dependin portions 18 are perforated to receive springeys 20 or other easily-detachable fastening means.

When the construction shown in Fig. 3 is employed, the forked portion 19 is likewise perforated to receive spring-pins or other fastening means 21.

The fuel-supports are precisely alike and are therefore interchangeable.

The plates 16, with their wings 17 and other portions, may be of any required length and any required number may be employed, and When-one section is burned out or broken it can be easily replaced and the grate-bar restored without the necessity for discarding the remaining and unburned fuel-supports and the supporting devices. The life of the device is thus materially increased and its value and efiiciency correspondingly increased.

The supporting devices and the fuel-supports carried thereby are thus disposed entirely below the upper face of the bearings 12 13, so that the steadiness of the device is materially increased and all tendency to lateral displacement obviated. The upper faces of the bearings 12 13, plates 16, and wings 17 being constantly flush with each other present no obstruction to the poker or other implement employed in clearing the grate of clinkers or in stirring the fuel to releasev the ashes and clinkers and cause them to fall through the interstices between the bars and fuel-supports.

Havmg thus described the invention, what is claimed is In a grate-bar, a supporting device comprising end bearings having vertical dependmg portions and with a bar extending between the lower terminals of said depending portions and arranged side by side in the fire- IIo chamber, fuel supports consisting of'plates 10 the line of movement' of the implements employedin manipulating the fuel upon the grate-bars, and: means for: detachably coupling said plates to said bar.

Intestimony that I claim the foregoing as my own I have hereto afiixed my signature 15 in the presence of two witnesses.
